The Charlotte Observer reports Mothers of Murdered Offspring sponsored the Thursday night vigil, calling attention to the death of a man who police say was fatally shot when he allegedly tried to rob a convenience store.

A statement from police says officers were called by someone at the vigil who said a person pulled a gun and began firing at people.

When officers arrived, they found that most people had fled, and there were no shooting victims. But police learned that there were four victims, each of whom had called 911 from a different location.
